Advantages that make the difference

Patented scraping technology

The rollers on Kärcher's floor cleaners are continuously wetted with fresh water; the dirty water is scraped off and collected in a tank.

Our floor cleaners don't have a suction fan, so they're incredibly slimline, easy to manoeuvre and quiet. The central roller drive ensures perfect edge cleaning.

Floor Cleaner patented scraping technology

20% better cleaning results than with a mop*

Your floor is your stage. Our floor cleaners leave your floor shining – cleaning approx. 20 per cent more thoroughly and requiring far less effort than any mop.* Instead of wiping dirt back and forth, the automatically powered rollers with self-cleaning function simply absorb it and then transport the dirty water into a separate tank. In doing so, our cleaners leave behind so little residual moisture on the floor that the show can go on in just two minutes. Thorough cleaning removes up to 99.9 per cent of all common household bacteria from all common household hard floors.****

Cleaning results achieved by floor cleaners

Go to the overview

You can use the following detergents with the floor cleaner:

Multi-purpose floor cleaner RM 536, order number 6.295-944.0
Stone floor cleaner RM 537, order number 6.295-943.0
Floor care for sealed wood RM 534, order number 6.295-941.0
Floor care for oiled/waxed wood RM 535, order number 6.295-942.0
Natural floor cleaner RM 538N, order number 6.296-286.0

Only use Kärcher detergent, and for the best possible cleaning results, make sure the correct dosage is used.

Using other detergents can damage the device and void the warranty.

Using detergents from other manufacturers or using too much detergent can cause an excess of foam to develop and can cause the device to shut down automatically before the dirty water tank reaches the maximum fill level.

The microfibre rollers of the floor cleaner are machine-washable up to 60 °C using liquid detergent. Important: do not use fabric softener.

The rollers should be replaced every 6 to 12 months, depending on the frequency of use.

Our floor cleaners don't have a suction fan, so they're incredibly quiet.

Volume of floor cleaners:

  • FC 2-4: 55 dB(A)
  • FC 4-4: 57 dB(A)
  • FC 7: 59 dB(A)
  • FC 8: 59 dB(A)

The drive of the rollers is not at the side of the cleaning head, but in the middle between the two rollers. This means that the cleaning track is interrupted by a narrow strip, but optimal cleaning of corners and edges is possible.

  1. Empty and reinsert the dirty water tank
  2. Put the device in the cleaning station
  3. Fill the fresh water tank (without detergent)
  • FC 8: go to the "Device cleaning" menu item.
  • FC 7 and FC 4-4: press and hold the on/off switch + button for adjusting the cleaning level for three seconds.
  • FC 2-4: no self-cleaning function available.

The self-cleaning process takes around 110 seconds (FC 8 and FC 7) or 90 seconds (FC 4-4).

Thorough cleaning with Kärcher floor cleaners removes up to 99.9 percent of all common household bacteria from all common household hard surfaces.

No, the FP 303 is not suitable for this because the rotational speed is too high.

Application questions

Kärcher floor cleaners can be used on all hard floors, be they wood, stone or plastic. The rollers do not cause any damage such as scratches on the surfaces. Do not hold the device still in one spot; instead, always keep it moving.

RM 534 detergent (order number 6.295-941.0) is ideal for cleaning sealed wooden floors (e.g. parquet, laminate).

For cleaning oiled/waxed wooden floors, RM 535 detergent (order number 6.295-942.0).

For cleaning stone floors, RM 537 detergent (order number 6.295-943.0).

To achieve good cleaning results with the floor cleaner, please note the following:

  • Wash the rollers in a washing machine at 60 °C before first use and when dirty.
  • If the rollers are too dry, you can wet them by activating boost mode (only applies to the FC 2-4 and FC 4-4). Move the device back and forth until the rollers are sufficiently wetted.
  • Clean the floor multiple times with the floor cleaner without using detergent. This removes residue of old detergent from the floor.
  • Only use Kärcher detergent and make sure the correct dosage is used. Observe the recommended dosage on the detergent bottle. Using too much or not enough detergent can lead to poor cleaning results.
  • Carry out device self-cleaning (only on the FC 8, FC 7 and FC 4-4).
  • Clean the hair combs regularly.

The dirt is picked up most effectively when the handle is 80 centimetres above the floor. The tolerance is between 65 and 90 centimetres.

During the forward movement, the dirt on the floor is first moistened. The majority of the dirt is picked up during the backward movement. Slow forward and backward movements also achieve the best cleaning results as this gives the device the time it needs to pick up dirt thoroughly.

The 4 V Battery Power charger fully charges a 2.5 Ah battery in around 2.5 hours. The 4 V Duo Battery Power fast charger can charge up to two 2.5 Ah batteries in just 70 minutes.

The remaining run time always refers to the battery with the lower remaining capacity.

Maintenance

It is not necessary to descale the floor cleaner as limescale only settles at temperatures above 70 °C. The acid of the decalcifying agent can also cause damage to your device.

If the floor cleaner develops unpleasant odours while cleaning, you can do the following:

  • Wash the rollers in a washing machine at 60 °C (important: do not use fabric softener)
  • Always use fresh water and do not leave water to stand in the tank after you have finished cleaning
  • Rinse the dirty water tank and fresh water tank thoroughly after each use
  • Clean the inlets and filters regularly, as described in the operating instructions
  • Residues of old cleaning detergents that are loosened from the floor during cleaning can also produce unpleasant odours

Troubleshooting

If the floor cleaner rattles loudly when switched on, it is possible that the rollers are too dry or have become deformed.

If the rollers are too dry, activate boost mode (only on the FC 7) and move the device back and forth until the rollers are sufficiently wetted. Alternatively, you can wet the rollers under the tap.

To prevent the rollers from becoming deformed, always store the device on the parking station provided and never store it directly on the floor.

  • Charge the battery.
  • Disconnect the charging cable, as the device cannot be operated with the charging cable plugged in.

The FC 7 may overheat at high ambient temperatures, when used with dry rollers or when used on carpet. Leave the device to cool down for around 2.5 hours. The device can only be switched on again once it has cooled down. It is possible to charge the FC 7 while it is cooling down.

If the rollers won't turn, this could be because they are blocked, not wet enough or because the motor is blocked, for example due to excessive pressure on the rollers or coming into contact with a wall.

If the motor is blocked, switch the floor cleaner off and on again.

 If the rollers are blocked:

  • Remove the rollers and check whether anything is jammed in the rollers.
  • Check whether the rollers are screwed into the roller holder as tightly as possible.
  • Check whether dirt has gathered in the hair filters in the floor head and, if so, remove it.
  • Check whether the hair filters are correctly inserted. To do this, remove the hair filters and then reinsert them again.

If the rollers are not wet enough:

  • Switch the device off, remove the hair filters and switch the device on again without the hair filters fitted. Press the boost button and move the device back and forth until the rollers are sufficiently wetted. Then you can reinsert the hair filters.
  • Alternatively, remove the rollers and wet them under the tap.
Graphic FC Error

As soon as the dirty water tank on the FC 7 exceeds a volume of 200 millilitres, the automatic device switch-off function is activated.

Using detergents from other manufacturers or using too much detergent can cause an excess of foam to develop and causes the device to shut down automatically before the 200 millilitres is reached. This is why we recommend that you use only Kärcher detergents and pay close attention to the correct dosage.

If the display indicates the dirty water tank is full even though the tank is empty, it is possible that the contacts that detect the fill level are dirty. Clean the contacts with a damp cloth.

If the fault persists, please contact one of our service partners or send us your device for repair.

 

FC FAQs

If the "Fresh water tank empty" error message appears even though the fresh water tank has been filled, this may be because deposits of detergent are covering the contact surfaces of the sensor. If this happens, remove the fresh water tank and the foam filter beneath it and use a cotton bud to clean the contact surface of the fresh water sensor. The contact surface can be found in the water inlet hole.

Illu FC

If your floor cleaner won't pick up dirt, take the following steps:

  • Fill the fresh water tank and insert it into the device, ensuring it is securely in place.
  • Insert the dirty water tank correctly, so that it audibly clicks into place. Also check whether the cover of the dirty water tank is correctly in place (locking tab must slot into the corresponding recess).
  • Insert the hair filters and rollers correctly into the device. The rollers must be screwed into the roller holder as tightly as possible. Clean the rollers when they are dirty and replace them when they are worn.
  • Wet the rollers by activating the boost function (FC 7, FC 8) or under the tap. Move the device back and forth until the rollers are sufficiently wetted.
  • Clean the fresh water filter. To do this, remove the fresh water tank and the fresh water filter and clean the filter under running water.

The Kärcher floor cleaners are designed to wipe floors clean (no suction fan) and are perfectly suited for floors with a maximum height difference of 1 millimetre. Small 1-millimetre feet on the dirty water tank ensure the correct distance is maintained between the movable sweeping rim and the floor. This is necessary to ensure that the floor cleaner delivers a perfect mopping function while at the same time picking up coarse dirt (2-in-1). On very uneven tiled floors with gaps of more than 1 millimetre, this can cause problems as the movable sweeping rim can get caught and consequently damaged.

It is also possible that the studs on the underside of the dirty water tank have become damaged or worn. If this is the case, please contact the authorised customer service team.

  • Insert the hair filters correctly into the device.
  • Replace the rollers if they are worn.
  • Empty the full dirty water tank.
  • Push the dirty water tank into the device so that it audibly clicks into place. The dirty water tank must be securely in place in the device.
  • Check whether the hair filters are correctly inserted.
  • If the dirty water tank is damaged, please contact the authorised customer service team.
